wait for 790fx 750sb mb?

im putting a 2nd computer together for me to take to work. kind of a budget gaming system. i have everything already but i haven't opened any of it up. i bought the asus m3a motherboard but i'm thinking of returning it, i'm thinking of replacing with a crossfire mb.

64x2 6000, 4850 video card, 2gb ddr2 800mhz ram, 750w psu

now i hear those new 790fx with the 750sb are out early july.
what kind of price will i be looking at for one of those? around $200?
should i wait for one or does anyone else have any other suggestions on mb?

When my DFI 790FX-M2R came out it was $250, and then it had a little brother the M2RS that was $180...so I would expect the new boards to be between $150(no oc), $180-$210(decent oc), and $230-$270(best of the best)...if I had to guess.
